The purpose of this tutorial is to analyze the Stern-Gerlach experiment using matrix mechanics. The figure below is taken (and modified) from Thomas Engel's text, Quantum Chemistry & Spectroscopy . Silver atoms are deflected by an inhomogeneous magnetic field because of the two-valued magnetic moment associated with their unpaired 5s electron ([Kr]5s 1 4d 10 ).

Though Stern did not leave physics, he did go on to receive the Nobel prize in physics in 1944, “for his contribution to the development of the molecular ray method and his discovery of the magnetic moment of the proton”. 6.3 The Stern-Gerlach Experiment This experiment, ﬁrst performed in 1922, has long been considered as the quintessential exper-iment that illustrates the fact that the electron possesses intrinsic angular momentum, i.e. spin. It is actually the case that the original experiment had nothing to do with the discovery that the The Stern-Gerlach experiment uses atoms of silver.

2015-02-22 · The Stern-Gerlach Experiment The Stern-Gerlach experiment, performed by Otto Stern and Walther Gerlach , tested whether subatomic particles behaved like little magnets. To do this, Stern and Gerlach created a magnet with a bigger north pole than south, just like the one described above, and shot a beam of electrons with random orientations through the resulting magnetic field. Tutorial for Stern-Gerlach Experiment .

In the Stern-Gerlach experiment, a beam of atoms (assume ) is sent into a magnet with a strong field gradient. The atoms come from an oven through some collimator to form a beam. The beam is said to be unpolarized since the three m states are equally likely no particular state has been prepared.

[13] Strictly speaking, Stern and Gerlach believed that they had found They thought their experiments confirmed Sommerfeld's old quantum theory (1916),

The classic Stern-Gerlach Experiment shows that atoms have a property called spin. Spin is a kind of intrinsic angular momentum, which has no classical counterpart. When the z-component of the spin is measured, one always gets one of two values: spin up or spin down.

Aparelho de Stern-Gerlach.png 398 × 182; 10 KB. Stern-Gerlach Experiment The first Stern-Gerlach experiment was in 1922, long before the discovery of electron spin with which it is now associated. It was an attempt to prove the existence of "space quantization," the limitation of the direction of angular momentum to a few space directions, as hypothesized by Niels Bohr and Arnold Sommerfeld. This straightforward analogy is especially useful to understand Stern-Gerlach experiments that involve a sequence of Stern-Gerlach apparatuses with each one being rotated with respect to the next one, because they can be explained by using the same mathematical model of states and measurements like that of a sequence of calcite polarizers; i.e. essentially, by using Malus law.

It was an experiment that, in fact, people were extraordinarily confused. It was not clear why they were doing it. And for quite a while, people didn't understand what they were getting, what was happening with it.

The Stern–Gerlach experiment involves sending a beam of silver atoms through an inhomogeneous magnetic field and observing their deflection. The results show that particles possess an intrinsic angular momentum that is closely analogous to the angular momentum of a classically spinning object, but that takes only certain quantized values. In 1922 Otto Stern and Walther Gerlach performed a seminal experiment in the history of quantum mechanics. In its simplest form, the experiment consists of an oven that produces a beam of neutral atoms, a region of space with an inhomogeneous magnetic field, and a detector for the atoms, as depicted in Fig. 1.1. Stern-Gerlach experiment, demonstration of the restricted spatial orientation of atomic and subatomic particles with magnetic polarity, performed in the early 1920s by the German physicists Otto Stern and Walther Gerlach.

Their famous experiment of 1922 has since been repeated many times with a variety of quantum particles.
